Senate is the second most commonly used traditional Chinese medicine, which has the effects of Shengjin, thirst-quenching, clear lung, and nourishing. We have found through on-site investigation and literature review that the actual use of ginseng leaf in Sichuan is as many as 8 species, all of which are stems and leaves of Panax species, and the literature on the origin of ginseng leaf is not uniform. Different regions vary. In order to ensure rational use of drugs and develop and utilize resources of Panax species, we conducted thin layer chromatography and total content determination of total saponins and total saponins in the eight species of collected ginseng. The results are now reported. I. Methods and Procedures 1. Extraction, separation and determination of total saponins Quantitatively weigh crude drug powder and place it in a Soxhlet extractor. Degreasing with ether until the leachate is nearly colorless, and the medicinal material is shaken at room temperature
